Abstract
We investigate the sensitivity of the semileptonic processes $e^+e^-\to\ell^-\bar{\nu}_\ell\; q\; \bar{q}'$, $\ell=e\;\mbox{or}\;\mu$,on the non-standard trilinear gauge couplings, using the optimal observables method at Linear Collider energies. Our study is based on the four-fermion generator ERATO. Taking into account all possible correlations between the different trilinear gauge coupling parameters, we show that they can be measured with an accuracy of 10-3 to 10-4 for typical Linear Collider energies and luminosities.
